RAIL-CHAIR.

more especially where the flat-bottomed rail is use-d.

The objects of our invention are: 1st, to provide perfect safeguardsagainst the upsetting of the rail; 2nd, to provide side supports of therail; 3rd, to provide means which minimize the cutting of the rail inthetie; 4th, to provide a rail-chair which can be easily removed andreplaced; 5th, to provide safeguards against creeping; 6th, to provide amore efficient, simplified,and lowcost article; 7th, to providesafeguards against spreading of the gage of the track.

Other objects will appear from the hereinafter description.

The invention is a rail-chair having wedge shaped, double plates, oneupon the other, of which the thin edges are in opposite directions,presenting when in place a. uniform thickness of metal under the rail, aflat surface against the tie, with the downward flange at. the edge ofthe tie, and pre-- senting a flat surface to the flat bottomed rail, aclamp space over the flange of the rail on both sides, and side supportsto the web of the rail.

When spiked to the tie in its effectual po sition and adjustments, ourimproved railchair is fastened to the tie by a spike through a hole ineach end of the chair through both plates, clamping the rail to the tieby a positive look by means of the cutaway space in the braces, pressingthe braces againstthe sides of the rail, and holding the rail fromcreeping by means of the flange down the side of the. tie.

In the accompanying drawings made part of this specification, Figure 1is a perspective View of the rail-chair spiked to the tie, a part lengthof which is shown, and clamping a piece of a rail, showing in the wholea complete rail-seat; Fig. 2 is a perspective view of the separate partsof the rail-chair; 1

-fication showing pairs of side braces, two on each side of the rail.

A designates the rail-chair as a whole.

B is a side brace integral with the top, wedge shaped leaf of the bottomof the rail-chair, so shaped on its under side as to have a cutaway partb, which fits over the flange of the rail for the whole width of the Webof the rail. I

B 1s a brace, preferably smaller, integral with the bottom wedge-shapedleaf C, havof the rail.

The slde braces B and B may be in pairs on each leaf, as shown in Fig.4.

chair; C is the bottom leaf thereof; D is a wide tongue of the wedgeshaped leaf C, and E is a slightly wider groove in the top leaf C,wherein the tongue D fits and slides. D is a narrower tongue of the topleaf in the modified form shown in Fig. 4. E is a narrower groove in thebottom leaf, adapted to receive the tongue D, in which it slides. F is aside flange on the leaf C, extending downward and adapted to fit againstone side of the tie. G is a tie or wooden sleeper of a railroadroad-bed.

H is a railroad rail.

and through the bottom leaf, C, registering when the leaves are in placeat the rail-seat and the braces B and B- are snug against the sides ofthe rail.

K is a spike through the holes I into the tie G firmly holding theleaves C and C in their effective locking position, and fastening therail-chair firmly to the tie.

in constructingrailroads involving our improved rail-chair, the ties andrails are first laidin position; but instead of spiking the rail to thetie by the ordinary driven railroad spike/or screw spike, the rail isslightly pried up from the tie and the top \\'e(lgeshaped leaf Cinserted from the outside of the rail. between the rail and the tie, andthe bottom leaf C inserted under the top leaf C from the inside of therail, and the two driven together until the side braces B and B are snugagainst the web i of the rail. The holes I through both leaves flangewhen the brace is sung against theing a cutaway space 6 fitting over theflange C is the top wedge shaped leaf of the rail- I is a hole throughboth the top leaf C C and G, then register, and a spike is driventhrougheach pair of holes intothe tie, whereupon the construction is complete.Then adjusting the plate, the flange F is placed snug against the sideof the tie, and the flanges on other chairs are placed on the other sideof the tie, so that the clamped rail cannot move lengthwise withoutdragging the tie, and thereby the creeping of the track is prevented, orlessened.

In derailing accidents, where rails are spiked directly to the ties, itis readily seen that when the trucks of a passing train are swaying fromside to side, the flange of the wheels may lunge against the inside edgeof the head of a rail, tending to upset the rail outward, and puttingthe stress .on the inside spikes in a direction to draw the spikes; andthis is the weakest spot in roadbcd construction. By our improvedrailchair, we put this stress against the outside larger brace. Againstthis the rail cannot upset, unless the outside spike is sheared off, andwe thus transfer the force in operation from a drawing stress on theinside spikes, to a shearing stress on the outside spikes, and thelatter offers manyfold greater resistance to this stress than theformer. I

We do not confine-ourselves to the details of construction, but havedescribed our improvement in its best form, but by way of illustration,and not by way of limitation. For example, without showing all the variat-ions, we may omit the .groove and tongue wherein the wedge-shapedleaves fit, and may make the bottom leaf as wide as the top leaf; and wemay make the leaves flat instead of wedge shaped, and may make the sidebraces the full width of the top leaf or less, and may make the bracesinpairson both leaves, or on either; or may employ onlyone brace on eachleaf, for whether the plates are wedge shaped or not, or move togetherin tongue and groove, when the side braces are brought up snug againstthe web of the rail, and the two plates are spiked to the tie throughthe holes I, the braces are locked against the tie-and the strains areconverted as hereinbefore described; and thus we accomplish all theforegoing objects.

'We may obtain the objects of our invention in some degree by omittingthe holes I and spiking the plates at, the edge, the

same as a rail is now-spiked direct to the tie. a

By the use of our improvement, we reduce the shearing strain on thespikes and lag screws.

Having now described our invention, what we claim as new and desire tosecure by Letters Patent is i 1. In a rail-chair, two wedge-shapedbottom plates, overlapping when in place, and adapted to be inserted atthe rail-seat, the thin edges first, each carrying a clamp adapted tohold the flange of the rail, spike holes in each leaf which willregister when the plates are in place, and adapted to receivespikes'when in such position.

2-. In a rail-chair, two wedge-shapedbottom plates, overlapping when inplace, and

adapted to be inserted at the rail-seat, the

thin edges first, each carrying a clamp adapted to hold the flange ofthe rail, one of which clamps is also a side brace.

3. In a rail-chair, two wedge shaped leaves, a side brace on each, holesfor both leaves, each adapted to receive'a spike, and a side flangeadapted to fit the side of the tie.

4. In a rail-chair, bottom plates having a wedge-shaped channel in one,and a wedgeshaped tongue in the other, adapted to be inserted at therail-seat from opposite sides of the rail, each plate carrying a clampadapted to hold the flange of the rail, one of which clamps is also aside brace.

In witness whereof, wehave hereunto set our hands and afiixed our seals,at Stamford, in the county of Fairfield, and State of Connecticut, this9th day o f -April, 1912.
